 libgomp is the support library for OpenMP code emitted by GCC. Adding
 support for RTEMS needs roughly the following steps:

 * Move <semaphore.h> header file from RTEMS to Newlib. Due to license
 issue use the one provided by FreeBSD and modify it accordingly.
 * Add Autoconf code to detect presence of Newlib <semaphore.h>.
 * Add RTEMS tweaks to libgomp configure script.
 * Add RTEMS specific link-time configuration to select a special memory
 allocator for libgomp.
 * Add ability to control thread scheduler, priority, stack size, etc. via
 application configuration options/handler.
 * Add standard OpenMP tests to RTEMS testsuite.
 * Add documentation to user manual.
 * Do performance tests.
 * Add dedicated low-overhead barriers.
